Abstract


Pemantauan neurofisiologis intraoperatif (Intraoperative neurophysiological monitoring/IONM) pada operasi yang rentan mencederai saraf sangat penting untuk menunjang proses keputusan medis intraoperatif dan pada akhirnya mengurangi angka morbiditas. Operasi meningioma foramen magnum sangat berisiko cedera saraf dan morbiditas sehingga menjadi kandidat yang cocok untuk penggunaan IONM. Cakupan manajemen anesthesia pada operasi yang menggunakan IONM adalah pertimbangan tentang pilihan dan dosis obat anestesia yang digunakan serta perhatian terhadap kestabilan homeostasis pasien. Pemahaman yang baik oleh dokter bedah, anestesi dan neurologi akan membuat tindakan operasi berjalan dengan lancar dan mencegah terjadinya komplikasi intra dan pascaoperasi. Seorang wanita umur 39 tahun dengan keluhan utama nyeri kepala belakang sejak 2 bulan yang lalu. Berdasarkan anamnesis, pemeriksaan fisik, dan pemeriksaan penunjang pasien di diagnosis tumor meningioma pada regio foramen magnum. Pasien dilakukan operasi kraniotomi removal tumor dengan panduan IONM dalam posisi park bench. Lama operasi kurang lebih 14 jam. Pascaoperasi pasien tidak dilakukan ekstubasi dan dirawat di ICU sehari.

 

Intraoperative Neurophysiological Monitoring (IONM) during Anesthesia for Meningioma Foramen Magnum Surgery

Intraoperative neurophysiological monitoring (IONM) in a surgery that is prone to neuronal injury is very useful to guide intraoperative decision makings and to reduce morbidity. Foramen magnum tumor surgerycarries a very high risk for neuronal injury, and thereforeapplication of IONM would be advantageous. The termsof anesthetic management in IONM-guided-surgery are the selection of anesthetic agents with limitation of the dosageswhileremain focusingon stability of patient’s homeostasis. A thorough understanding and communication among surgeon, neurologist and anesthesiologist are important to createan uneventful procedure and to reduce intra and postoperative complications.A 39 years old female with severe headache for 2 months was diagnosed with meningioma at foramen magnum based on history, physical examination, and advanced examination procedures. The patient was underwent tumor removal guided by IONM on park bench position. The duration of surgery was 14 hours. The patient was not extubatedpostoperatively and admitted to ICU for a day.
